Two moles of an ideal gas undergo the following process `:`
`(a)` a reversible isobaric expansion from `( P` atm, `V L)` to `( P` atm , `2V L)`.
`(b)` a reversible isochoric change of state from `( P` atm , `2V,L)` to `(P//2` atm, `2V L)`
`(c )` a reversible isothermal compression from `(P//2` atm, `2V L)` to `(P ` atm, `V L)`.
Sketch with labels each of the processes on the same `P-V` diagram.
